Lasik eye surgery uses a laser to reshape the cornea from under the corneal flap. A particular type of laser is used in this procedure. The purpose of having this surgery done is to improve vision and correct refractive errors. Having Lasik eye surgery can reduce or eliminate the need for eyeglasses or contact lenses. In the procedure, the front covering of the eye (the cornea) is reshaped.
The eye surgeon makes a hinged flap in the cornea and pulls back the flap, exposing the tissue of the cornea. This tissue is then reshaped to correct the patient's vision problems. The flap is allowed to shut, and no sutures are ever used in the procedure.

Lasik eye surgery benefits patients with myopia, hyperopia, and astigmatism. Myopia causes near objects to be viewed while distant objects become blurry because of a mismatch between eye length and focusing strength. Hyperopia, the same mismatch, causes distant objects to be viewed clearly, while near objects become blurry. People with astigmatism suffer from corneal or lens distortion that makes everything appear blurry. It is common for someone to suffer myopia or hyperopia with astigmatism.
Eyeglasses and contact lenses adjust the light to compensate for refractive errors from myopia, hyperopia, or astigmatism. Eyeglasses and contact lenses do not fix the problem with the eye; they bend light to make up for the distortion. Lasik eye surgery is a physical correction to the vision that can eliminate the need for eyeglasses or contact lenses.
Conventional surgery uses a direct pattern based upon the
patient's prescription to correct refractive errors.
If you have vision impairment due to myopia, hyperopia, or astigmatism, it would be a good idea to consult an eye doctor about the benefits of Lasik eye surgery. This treatment is becoming a commonplace substitute for conventional eyeglasses and contact lens prescriptions. Like any surgery, there are risks involved. Traditional Lasik eye surgery can result in halos in vision, night vision issues, or glare. There are other types of laser eye surgery wherein these risks are somewhat more mitigated. You should consult an experienced eye surgeon to decide what sort of procedure might be most beneficial to you.
Lasik eye surgery can physically correct a problem that
contacts and glasses do not. There are many surgery centers where surgeons work
to specialize in these procedures. There is bound to be one near you where you
can discuss treatment options and costs. Some people feel that Lasik eye
surgery is just a matter of vanity for people who no longer wish to wear
glasses or a matter of convenience for those now using contact lenses. When you
consider, however, that Lasik eye surgery is a physical correction to
distortion, you can make the argument that it is better to treat the condition
rather than just the symptoms.
